You have a 2G iPod touch, so you should be looking at the redsn0w section as the section you posted this in is for jailbreaking the original iPod touch (the one without speakers).

And if you're really, really novice you should be waiting for what they call an "untethered" jailbreak which will be super easy and consists of running a program on your computer and basically clicking through the arrows as you follow the steps and let the program work behind the scenes to jailbreak your device.

As of now there is a "tethered" jailbreak which is the manual way and requires many many steps to jailbreak your 2G iPod touch and it might be confusing and put your iPod touch at risk if you mess around with it not knowing what you're doing. You also need to re-jailbreak your iPod touch if you use the tethered jailbreak every time you turn it on because if you shut it off it removes the jailbreak from the device.
